Les Misérables

Without wishing to be too critical, I would suggest that this question gives away the vintage of the book (or at least one of the books) that provided these questions. Les Misérables celebrated its 30th anniversary in 2015, and ran at the Queen's Theatre until July 2019, when it closed to allow for theatre refurbishment. It then ran in a concert format at the Gielgud Theatre until 2 December, and an updated production was due to open at the original venue – renamed the Sondheim Theatre – on 18 December (eight days after these questions were asked in MQL).
